7/8 is the greatest
Answer:
The experimental probability of getting a 3 on a die is 30% which is approximately 13% more than its theoretical probability (17%).
Step-by-step explanation:
Theoretical probability of number 3 on a die:
Total no. of possibilities = 6
Probability of getting a 3 on a die each time it is rolled = 1/6
= 0.16667
= 17%
Experimental probability of number 3 on a die:
Total no. of rounds = 4
Rolls each round = 20
no. of 3s in round 1 = 6
no. of 3s in round 2 = 6
no. of 3s in round 3 = 5
no. of 3s in round 4 = 7
Total rolls = 20*4 = 80
no. of times 3 comes up = 6+6+5+7 = 24
Experimental probability of getting a 3 on a die
each time it is rolled = no. of 3s/total rolls
= 24/80
= 0.3
= 30%
Difference = 30% - 17% = 13%
Experimental probability of getting a 3 on a die is 30% which is approximately 13% more than its theoretical probability (17%).
Answer 6.5
Step-by-step explanation: or
Answer:
A) 440.44 units³
B) similar figures
C) 1486.485 units³
Step-by-step explanation:
Volume = ⅓× base area × height
= ⅓ × 110.11 × 12 = 440.44 units³
B) he doesn't have to make calculations again because the two pyramids are similar.
If the ratio of sides is given, he can find the other volume using:
(side1/side2)³ = volume1/volume2
(2/3)³ = 440.44/volume2
Volume2 = 440.44 × 27/8
Volume2 = 1486.485 units³
you can imagine this as a venn diagram. the "or" event would consist of everything in both sides and the middle of the venn diagram because you can choose form either event x <u>or</u> event y.
the "and" event would consist of everything in the middle of the venn diagram because you choice must be a part of both event x <u>and</u> event y.
the complement of an event is just everything that is not included in the event. for example, in a coin flip, the complement of heads is tails. in a dice roll, the complement of {1,2} is {3,4,5,6}
so if you come across these just think "either or" or "both and." and remember that the complement is everything excluding what is listed.
i apologize if this does not help, im not that great at explaining things
